Double lines in ubuntu guest

[bbrala]

Hi,

When i run provision multiple times, the hostfile seems to be populated with multiple sets of host definitions. Not sure why the filter doesn't work as intended.

if Vagrant.has_plugin?("vagrant-hosts-provisioner")
        config.vm.provision :hostsupdate, run: 'always' do |host|

            # Get list of all directories in folder above this file.
            paths = Dir.entries(projects_dir).select {|entry| File.directory? File.join(projects_dir,entry) and !(entry.start_with?(".")) }
            hosts = paths.map do |path|
                "#{path}." + config.vm.hostname
            end
            hosts.push("testing." + config.vm.hostname)

            host.hostname = config.vm.hostname
            host.manage_guest = true
            host.manage_host = true
            host.aliases = hosts
            host.files = [
                'provision/configuration/hosts.json'
            ]

        end
    end

Hostfile:
